We have documented the flash runtimes and behaviour in depth below. The features listed below with ** are only available via the IOS/Android Smartphone app
Solid: 2 hours max (the whole LED board stays on constant and does not react)
Flash: 10 hours max (the top and bottom sections of the board flash alternately. This mode reacts to both light and movement)
**Twin - 8-9 hours max (the whole LED board flashes. This mode reacts to both light and movement)
**Burst - 8-9 hours max (similar to flash, except each section of the LED board flashes longer. This mode reacts to both light and movement)
**Pulse - 3-4 hours max (one section of the LED will flash on constant, whilst the other section 2-3 times. This light mode will only react to movement and not react to light changes)
ECO- 30 hours max (this is only available via a 2nd button press after solid mode and reduces the light output significantly to extend runtime and is also handy for riding in a group so that it does not dazzle those riding close behind you. This mode reacts to both light and movement)
**Brake Mode - When braking, half of the LED board will light up and the other half will remain flashing. When you move again after braking the light will revert to flashing. The light will not react to light or any other movement except medium-hard braking.
Please note that this is for an ACE rear and whilst the front will behave similarly; the ACE front LED board is split into 3 different sections, whilst the rear is split into 2 sections.
